i wrote this some years ago for my grand children. It was published in my second book, Cloudscape And Landscape: poetic Echoes:

SEE-SAW

See-saw is played only as a pair,
up and down, in turns, we share.
One must be up, the other down,
no co-operation, both are clowns.
Senseless to prolong stay in the air,
touch ground again to go high is flair.
There are limits to get high and fast,
a careful ride is safe and fun will last.
Up and down, balance of life, is fair,
give and take, high or low, is funfair.
